Enterprise Solutions

Commercial, Industrial & Agribusiness Solar

Customized financial structures and specialized grids engineered for enterprise clients in Mindanao and Luzon.

C&I Financial Models

Zero Capital Outlay: Solar Leasing & PPAs

Avoid upfront capital expenditure. Under our Solar Power Purchase Agreement (PPA) or Leasing model, we design, install, and maintain the solar system on your rooftop. You only pay for the solar energy generated at a rate significantly lower than your local distribution utility (DLPC / Meralco).

EV Charging Integration

Future-proof your commercial facilities. We integrate smart level-2 EV charging stations with custom solar carports, allowing your corporate fleet or customers to charge directly from clean solar energy.

Agribusiness & Weak Grids

Poultry & Livestock Farm Solar Ventilation

High daytime temperatures in Mindanao increase livestock mortality and energy costs. We design high-reliability off-grid and hybrid solar systems to run farm exhaust fans and cooling pads, securing critical ventilation during peak sun hours.

Power Quality & Voltage Stabilization

Agricultural grid lines in rural provinces often suffer from severe voltage sags and power factor drops. We integrate power factor correction, voltage regulators, and battery buffering to protect sensitive agricultural machinery.

SCADA IoT Real-Time Monitoring

Monitor yield, performance ratio, and ROI in real-time. Our systems feature industrial-grade SCADA dashboards with automated email alerts and yield analytics accessible via mobile or desktop.

BIPV (Building-Integrated Photovoltaics)

Replace traditional building materials. We offer premium building-integrated solar glass, solar tiles, and facades that generate clean electricity while maintaining sleek architectural aesthetics.

Localized Utility Net-Metering Guides

We handle the entire engineering, safety, and regulatory compliance filing with your local Distribution Utility.

Technical Glossary

Learn about standard engineering terminologies in wind and solar operations.

BESS (Battery Energy Storage System)
A technology that captures energy at one time (e.g. during sunny peak solar hours) and stores it for discharge at a later time (e.g. during nighttime or blackouts).
BIPV (Building-Integrated Photovoltaics)
Photovoltaic materials used to replace conventional building materials in parts of the building envelope, such as the roof, skylights, or facades.
Net Metering
A billing mechanism that credits solar system owners for the electricity they add to the grid, allowing excess daytime solar production to offset nighttime utility charges.
LCOE (Levelized Cost of Energy)
The average net present cost of electricity generation for a power plant over its lifetime, used to compare different electricity generation technologies.
